I just use one Morphic project as one slide. I do this in full screen 
mode, which especially looks interesting as people are not used to the 
idea having a screen where you do not see any GUI elements and still 
can work in with ease. Well there are the flaps. I created my own flaps 
(parts bin) where I keep StringMorphs in different point sizes and 
colors to add to the consistency.

(Side note: well Tim, you see, I do not use a top menu bar .....)

I often have one central slide (like in the 'Worlds of Squeak') from 
where I can branch off to separate slides and come back to the point of 
departure - like a brain map with 'sub-brainmaps', where I have 
graphical links to. It is easier for me and the poeple as well to 
present something. (A kind of top-down approach).

The ProjectViewMorph links are very nice. If you have e.g. a dark blue 
background in the central slide it looks very nice. You can resize them 
to accomodate to your needs.

I often have another project apart called 'Slides' where I create the 
slides. A slide can be reused in different presentations then more 
easily.

I added a 'add-jump-to-project' menu entry to the class StringMorph, so 
any string in Morphic world can be a hyperlink to another project as 
well.

In addition I changed the snap in grid distance to a relatively large 
value, so that the elements are easier to align.

And what is really astonishing. If you have done these preparations 
mentioned above, you can work on the presentation during presenting, 
i.e. collect feedback and put it down for everybody to see (like on a 
whiteboard).

In fact Squeak can be used nowadays as a 'dynabook' if you are ready to 
take on some effort to customize it for your needs.

On an off I have been working on a HTML export function (using DIVs for 
RectangleMorphs and CSS for absolute positioning). It works quite 
nicely and in the not so distant future I will put it on SqueakMap. In 
the web browser I switch as well to full screen mode (often F11-key).
